Most of them are adjectives trying to describe you. Instead use action words—preferably verbs—that show your accomplishments. Here's a good list of them from Money Zine.

Showcase your latest volunteering experience

LinkedIn

Show off a personal side.

What you do out of the office says as much about you as anything else. Employers or work connections can get a sense of you as a person by reading how you spend your time.

Think over your year and update your volunteer info with the new stuff you did. Find this section by clicking on "edit profile" and then "volunteering and causes" in the right-hand bar.

And if you didn't volunteer at all in 2012, consider giving it a try over the holiday season or in 2013. Start by looking through VolunteerMatch.org.

Beef up your skills list

Use the hottest words as your skills.

The Skills section is one of the ways recruiters find you. "Skills" are trendy words that change all the time. Is it better to use "blogger" or "blogging"? Is it better to say "mobile applications" or "mobile phone apps"?

LinkedIn Skill search will tell you. Type the skill into the Skills search box and it will compare that term to a list of other similar terms and show you how popular each is. Edit your profile to use the most popular terms.

Don't forget about the skills you've used volunteering too. Maybe you cook, write, organize, manage people or projects as a volunteer. That counts. Just make sure you've filled out the volunteer section to explain that skill.

Follow some new "thought leaders"

Their posts will show up on your home screen. It's a good way to keep up with big topics in the year to come.

Follow them and their posts will show up on your LinkedIn homepage.

Snag a new recommendation

Add more endorsements over time.

Most people only beef up their recommendations when they go job hunting. But a bunch of new recommendations, especially from friends, are easy for recruiters to spot and ignore.

Lists of recommendations that span months or even years are more impressive. A good word from execs in your industry or at your company are the best, recruiters say.

Clean out your old groups and add new ones

Kill off the dead groups for new ones.

You may have joined a few groups early on, based on invitations or other outdated reasons. Don't feel limited to joining employee or alumni groups. Clear out the groups that you don't love and try some new ones.

Groups can be one of the best ways to expand your network. Having a group in common gives you a good way to break the ice with helpful professional contacts.

Follow your dream employers

LinkedIn

Follow companies in your dream industry.

Even if you love your job, it can't hurt to look, particularly if your dream job is still out there.

Where could you see yourself working? When you follow a company on LinkedIn, you can learn about job openings and make yourself seen by commenting on news in the company's activity stream.

Add some new apps and features

There are all kinds of add-ons apps to LinkedIn, from apps that let you find professional events in your town, hear about trendy business books, or see where your LinkedIn contacts are traveling.

Try a new one or two.

Ask a question, answer a question

LinkedIn

People have actually been offered jobs just because they did a great job answering questions on LinkedIn Answers.

Vow to step up your participation next year. You might enjoy sharing your expertise and you could find the answers you've been looking for.
